Abstract

Ocean deoxygenation is a growing threat to marine life worldwide but our knowledge of oxygen dynamics in tropical coastal regions is poorly resolved. Here we provide high-resolution oxygen data for five coral reefs throughout Almirante Bay, Bocas del Toro, Panama. This current dataset includes a six-month record of hourly temperature and dissolved oxygen concentration measurements on five coral reefs, with two loggers taking data at each reef, one from a shallow (3 m) location and the other from...

Methodology 

OnSET HOBO Dissolved Oxygen Loggers (Model U26-001) were calibrated with new optical caps using HOBOware Software. Calibration included a 100% saturation point and 0% saturation point, using 0% Onset’s zero-calibration solution, following the manufacturer instructions.

Loggers were deployed using Hobo Onset Shuttle and programmed to record hourly measurements. A copper antifouling cover was installed on each logger to reduce fouling. Loggers were then brought to the field sites and secured to concrete blocks on the seafloor. The face of the optical sensor was oriented to be perpendicular to the seafloor, so sediment was unable to collect on the surface.

Data were collected every 3-6 months. Sensor caps were replaced every 6 months with new, calibrated sensors.  

Sampling and Analytical Procedures

Loggers measured temperature (C) and dissolved oxygen (mg/L) hourly at their deployment location.
